A cat litter box should measure at least 1.5 times your cat's body length from nose to tail, according to AAHA and AAFP feline life stage guidelines. Provide one litter box per cat, plus one extra, following the rule recommended by the ASPCA and Purina. Scoop waste daily, keep litter 1 to 2 inches deep, and choose an open or covered design based on your cat's need for privacy versus your household's number of cats.

Bringing a cat home means preparing a comfortable place for it to relieve itself, and the litter box is one of the most important purchases a new cat owner makes. The right box, sized and placed correctly, directly affects whether a cat uses it consistently.
 
This guide covers the common types of litter boxes, how to size and place one, which accessories help with cleanup, and how much litter to use so your cat's bathroom habits stay consistent.

What Are the Common Types of Cat Litter Boxes?

Open Litter Boxes

Open litter boxes are simple, uncovered pans. They give a cat multiple ways to see the room and exit quickly, but they don't contain odor and don't stop litter from scattering onto the floor.

Covered Litter Boxes

Covered or hooded litter boxes have solid sides and a lid, with an entry flap. This design suits cats that prefer privacy, and it generally contains odor and scatter better than an open pan.

Disposable Litter Pans

Disposable litter pans are made from biodegradable material and are meant to be thrown away after use. They work well for travel or short trips, since there is no box to scrub afterward.

Self-Cleaning Litter Boxes

Self-cleaning litter boxes use sensors to detect when a cat has used the box, then rake or sweep waste into a separate bin automatically. This design suits busy households that can't scoop several times a day.

Sifting Litter Boxes

Sifting litter boxes use a perforated top tray over a solid bottom tray, so scooping means lifting and shaking rather than digging through litter by hand. This manual design saves time for owners who prefer not to use an automatic box.

How Big Should the Litter Box Be?

Litter box size affects whether a cat will use it consistently. According to AAHA and AAFP feline life stage guidelines, a litter box should be at least one and a half times the length of the cat, measured from the nose to the base of the tail. Most manufactured boxes fall short of this size, especially for larger cats.
 
Many Higooga customers with larger or multiple cats tell us that upgrading to a bigger box resolves inconsistent litter box use faster than switching litter brands. If your cat's box feels tight, a large storage container can work as a temporary substitute while you shop for a properly sized box.

What Kind of Design Makes Up a Good Litter Box?

A good litter box needs to be functional first. It should be easy to clean without spilling waste, easy for your cat to enter and exit, and sturdy enough to handle regular digging and scratching.
 
Match the design to your cat's mobility and preferences. Senior cats or kittens often do better with low-entry, open boxes, while healthy adult cats can comfortably use covered or top-entry designs.

How Many Litter Boxes Should You Have?

The generally recommended rule, cited by the ASPCA and Purina, is one litter box per cat, plus one extra.

Households with fewer boxes than recommended tend to see more litter box avoidance, since cats are sensitive to sharing a dirty box with another cat.

Which Litter Box Fits Your Situation?

What Accessories Do You Need For Your Litter Box?

A few accessories make daily litter box maintenance easier.

• A dedicated scoop: the Cat Litter Scoop with Container keeps a sizable scoop stored inside its own container, so cleanup and disposal stay in one place.
• A litter mat: the Double-Layer Non-Slip Cat Litter Mat traps scattered litter in its honeycomb layer so it can be shaken back into the box instead of tracked through the house.
• An odor purifier: the DownyPaws Smart Cat Litter Box Deodorizer & Pet Odor Purifier works well in compact apartments or with open litter boxes, where odor control matters most.

Where Should You Set Up Your Cat's Litter Box?

Place the litter box somewhere your cat can enter and exit freely, in a quiet spot away from heavy foot traffic. Most cats prefer a location where they can see the room and have more than one way to leave if needed.
 
In multi-cat homes, spread boxes across different rooms rather than lining them up together. This keeps one area from feeling like a shared bathroom, which can discourage some cats from using it.

How Do You Choose the Right Cat Litter?

Litter choice affects how consistently your cat uses the box. Take a look at our guide to choosing the best litter for your cat to compare clumping, unscented, and specialty litter types.

How Much Litter Should You Use?

According to the ASPCA, most cats prefer a shallow bed of litter, around 1 to 2 inches, rather than 3 to 4 inches. Deeper litter does not reduce how often you need to scoop, and many cats avoid boxes that feel too full.

Follow the manufacturer's guidance for your specific litter brand, and adjust based on your cat's digging habits. Cats that dig extensively may do better with slightly more litter, up to about 3 inches.

How Often Should You Clean the Litter Box?

Scoop solid waste at least once a day. The ASPCA recommends a full litter change and box wash with mild, unscented soap about once a week for one cat, more often in multi-cat households.

Avoid ammonia, bleach, or strongly scented cleaners, since cats are sensitive to smell and may avoid a box that smells like cleaning products.

How Can You Make Sure Your Cat Uses the Litter Box?

If a cat stops using its litter box consistently, start with the basics: check the box size, confirm there's enough clean litter, and rule out any physical obstacles blocking access.

• Confirm the box is large enough for your cat to turn around comfortably.
• Keep enough litter in the box and scoop daily.
• Remove obstructions or anything that could cause stress near the box.
• Try a different litter if you recently switched brands.
• Talk to your veterinarian if the behavior continues, since litter box avoidance can signal a medical issue.

FAQ

Do kittens need a different litter box than adult cats?
Yes. Kittens need a box with low sides so they can climb in easily, usually until they are a few months old. Standard or covered boxes can be too tall for very young kittens to enter comfortably, which may lead to accidents outside the box.

Can two cats safely share one litter box?
Two cats can share a box, but most behaviorists recommend at least one box per cat, plus one extra, to reduce competition and stress. Sharing a single box more often leads to litter box avoidance, especially if one cat is possessive of the space.

Is scented cat litter safe to use around a pregnant person?
Scented litter itself isn't the main pregnancy concern; toxoplasmosis from cat feces is. Pregnant individuals should avoid scooping litter boxes when possible and, if they must, wear gloves and wash their hands thoroughly afterward, following standard prenatal care guidance.

Why does my cat scratch the floor next to the litter box instead of digging inside it?
This can signal that the box feels too small, the litter texture is uncomfortable, or the box isn't clean enough. Some cats also scratch nearby surfaces as a scent-marking behavior that is unrelated to the box itself.

How long can a litter box go without cleaning before it becomes a health risk?
A box left unscooped for more than a day or two allows ammonia and bacteria to build up, which can cause respiratory irritation and encourage cats to eliminate elsewhere. Daily scooping keeps ammonia levels low and reduces this risk.

What should I do if my cat suddenly stops using a litter box it used before?
Sudden avoidance often points to a dirty box, a litter change, a new location, or a medical issue such as a urinary tract problem. Rule out cleanliness and location first, and consult a veterinarian if the behavior continues for more than a day or two.

Key Takeaways

• Size the litter box at least 1.5 times your cat's body length, per AAHA and AAFP guidelines.
• Keep one litter box per cat, plus one extra, per ASPCA and Purina recommendations.
• Scoop daily and do a full litter change about once a week.
• Use 1 to 2 inches of litter; deeper litter doesn't reduce cleaning needs.
